PAVING-BRICK.

S PECIFICATION forming part of Letters Patent No. 447,612, dated March 3, 1891.

Application filed June 26, 1890- Serial No. 356,910. (No model.)

To all whom it may concern.-

Be it known that I, ATHELSTAN O. J ONES, of Zanesville, in the county of Muskingum and State of Ohio, have invented a new and useful Improvement in Paving-Bricks, of which the following is a specification.

The object of my invention is to provide a durable, strong paving brick or block for the paving of streets, alleys, and roadways, which brick or block will pack in the road-bed in close juxtaposition with each other and be firmly held in place by the intervening filling of cement or pitch without wasteful use of the latter material.

It consists in the peculiar construction of the brick or block, which I will now proceed to describe with reference to the drawings, in which Figure 1 is a perspective view of the brick from one side. Fig. 2 is a similar view of the brick from the opposite side.

In the drawings the brick is shown in the position which it occupies when laid in the road-bedthat is to say, the upper face a is the wearing-face, which is exposed to the tread of traffic.

The brick is of greater vertical depth than width, and its upper face has its edges rounded on all four sides, so as to form seams or joints between the bricks, which furnish a hold for the feet of the teams to prevent slipping and for the further purpose of giving an opening between the tops of the bricks whenlaid sufficient to receive the pitch or cement that is flowed between the bricks to bind them tightly in the road-bed.

Upon both sides of the brick are formed a series of parallel grooves. Upon one side these grooves 12 are arranged diagonally and upon the other side the grooves b are arranged vertically. These grooves open into the rounded edges of the top of the brick, but do not quite eXtendto the bottom of the brick, the bottom edges of the brick being square and full size. The function of the grooves is to act as channels or leaders for the hot pitch or cement to carry it down uniformly between the bricks and tightly and uniformly fill the space between the same, so as to hold them solidly in place. rying these grooves to the bottom of the brick is to prevent waste of the pitch, which would (if the grooves went to the bottom) drain away underneath the brick.

At the ends of the brick are horizontal grooves 6 which communicate with the diagonal grooves and are designed for the same purpose of receiving the pitch or cement.

The upper and lower faces of the brick may be glazed, if desired but the sides and ends should be left unglazed in order to give the pitch or cement a chance to take a more firm hold thereagainst.

The grooves in the sides of the brick per-' mit the bricks to be laid on their flat sides while being glazed. These grooves, in cansing the molten pitch or cement to flow down between the bricks, causes it to be distributed to both the sides and ends, preventing water and moisture from getting to the foundation and also making a strong bond and preventing any settlement due to soft spots being formed in the foundation from the access of water. By thus preserving the foundation and keeping the top faces to a perfect level the life of the pavement will be nearly doubled and the same foundation may be used again when a new surfacing becomes necessary. These grooves also enable the bricks to' be firmly locked to each other when laid, the grooves in one brick crossing those in the next.

Having thus described my invention, what I claim as new is A paving-brick having rounded upper edges with diagonal grooves Z) upon one side and vertical grooves b upon the other, the said grooves running out at the top into the rounded portion, but stopping short of the bottom edge, substantially as and for the purpose described.
